Abstract

Biopsy needles are devices that have been used for intravenous therapy. However, the high susceptibility of needles results in signal loss and distortion which makes the location of needles hard to identify in the MRI images. A variety of approaches has been proposed to quantify the susceptibility of the materials being imaged because susceptibility is an intrinsic property that can be used to make a good contrast between different materials. Although previous techniques on susceptibility mapping seem quite effective, they usually consume too much time due to the iterations. In this paper, a method based on Wiener filter is developed to improve the speed of susceptibility mapping. Simulation and phantom experiment demonstrate the effectiveness and high efficiency of the proposed method.
